Aim To taste water of known salinity concentrations and compare them to known salinity levels of the sea and Murray River. Hypothesis
I think the sea water will taste the saltiest. Materials
·5 litres of water ·5 one litre containers ·Salt ·Measuring cones marked on side at 1.2cm, 2.3cm, 3.4cm, 7.5cm and 11.7cm ·Plastic Spoons Procedure
1.Measure 1.2cm of salt into the cone. 2.Pour salt into prepared 1 litre container. 3.Repeat steps 1 and 2 for the remaining 4 measurements. 4.Wait for salt to dissolve in the water. 5.Use a disposable spoon to taste the water from each container. (New spoon for each tasting). Conclusion
I have discovered that there is a HUGEdifference between the amount of salt between the Fresh Water and the water from the Murray River
How Salinity Affect the Growth of Plants
Last week we conducted an experiment to see how salinity affects the growth of plants by planting seeds into two different cups one labelled ''No Salt'' and the other labelled ''Salt''.
After seven days we could conclude that the plants with no salt grew strong and healthy, while the plants with salt did not grow or change.
We discovered that plants can not grow with salt due to the fact that salt absorbs all the plants nutrients and water.
A Taste of salt
